Step by step instructions fro addinng SPF record in SBS 2003 required

I am pulling my hair out trying to add an SPF reccord to my SBS 2003.
I am getting massive ammounts of spam email that has spoofed my email address.
I have SBS 2003 SP2 with a static public IP address. I use SMTP email that is sent directly to my IP address.
There is no SPF record for my domain name (using microsoft Sender ID Framework SPF Wizzard) but an IP address (I presume my ISPs) is listed in A records. mail servers listed in MX records list my domain and IP address.
In the DNS server on my SBS box there is no external listing for my domain - just the .local domain.
I have tried using creating an SPF record at openspf.org but what do I do with the txt that it created. Some are saying that it should go in the DNS on my server others say it has to go on the ISPs server.
Help please.

BT is my ISP but I host my own mail and the A record is pointing to my IP address. When I use openspf.org, the IP address that they automatically list up as my A record is held at MEGANAMESERVERS.COM this is a BT server but is only used for www and ftp.
As far as adding the SPF text file to external DNS, I have no external DNS enties listed in my SBS Server on the DNS server so how do I add the DNS entry?

Are you tired of cycling through the same browser tabs everyday to close the same repetitive tickets? In this webinar JumpCloud will show how you can leverage RESTful APIs to build your own PowerShell modules to kill tickets & tabs using the PowerShell command Invoke-RestMethod.

Hi adiloadilo,
I have checked the IMF and that is already setup - I can remeber setting that a few years ago.
I have entered my domain in the MX lookup and the result is mail.mydomainname.co.uk and my public static IP address. if i do a DNS lookup i get Type = A , domain name = mydomanname.co.uk and IP address = an other public IP address that belongs to my ISP. But they say they have nothing to do with my mail as it goes directly to my public IP address and skips past them.
I am still not sure what you are calling my extrnal dns enties. Are these entries listed in my dns server in the SBS box or are they on some server in cyber space?

ok , you said that you found mail.mydomainname.co.uk in the mx lookup ? who controls mydomainname.co.uk ? if you need to add another a record for example mail2.mydomainname.co.uk, who can do that ? if you need to change that mail.mydomainname.co.uk to point to that public address ? if you can not do all this tasks on that domain , then you do not have access to that domain and you should contact your isp to properly change your SPF records as they are the only admins who can change mail.mydomainname.co.uk settings .

Hi,
I can maage my domain on my ISPs site. It looks like I can add an mx record an a record or antext message. I presume this is where I add the spf txt record.

Thanks for the help.
its late here so I will get that sortet out tomorrow morning. Then all I have to do is work out how to do the same thing for another customer that has a totally different configuration.
Thanks again
